35. Drill out the first hole on each leg of the Tip Bow to #30. Locate and mark
the trailing edge side of the Tip Bow.
NOTE: The trailing edge side has an
additional hole drilled (this hole is NOT used on the S-7S). Refer to
FIGURE 05-35 . Insert the Tip Bow into Leading and Trailing Edge Spar
and cleco Tip Bow through the FWD side of Leading Edge Spar and the
AFT side of Trailing Edge Spar. Make sure the orientation of the Tip Bow
is correct. Center the pre-drilled #40 hole in the Tip Bow with the
pre-drilled #30 hole in the Spars and chase drill the Tip Bow to #30 and
cleco. Remove one cleco at a time and drill out the four holes to #11.
36. NOTE: The Tip Bow is purposely under bent. This forces a curve into the
Tip Bow when installed. Once the fabric is installed, this curve will
straighten. Rivet the Tip Bow to both the Leading and Trailing Edge Spars
with 3/16" stainless steel rivets.
37. Compression Tubes may be final-bolted in place. Do NOT final-bolt Drag
Braces at this time, as they will need to be removed for installation of Wing
Ribs. Instead, temporarily secure Drag Braces with bolts and nuts finger
tight.
